Pre-Detection Recordings: Any in existence, declassified and accessible–?

Many thanks to SWLing Post contributor, Chip, who writes:

I remember reading a number of years ago that the NRO/NSA was the largest consumer of magnetic tape, utilized for pre-detection recordings of various spans of spectrum, all over the world.

I’m wondering if those tapes become declassified at some point, and if they are available through FOIA requests. Were they just bulk erased, destroyed or sold at GSA auction along the way.

Do you know if anyone has ever queried into their existence, and if they have been electronically preserved to some other digital medium?

The idea that our government records huge chunks of spectrum, fuels thoughts in my mind of huge spans of non-classified spectrum from across the years. All the DX shortwave outlets captured for posterity.

Thank you for sharing this note, Chip.

Of course, I’ve always been interested in adding recordings like this to the Radio Spectrum Archive. If these recordings exist, I would love to see them added to the Internet Archive–who stores Radio Spectrum Archive recordings– so that they could be shared and enjoyed by all.

The Icom IC-705: Is this really a new holy grail SWL/BCL receiver?

The Icom IC-705: Is this really a new holy grail SWL/BCL receiver?

by 13dka

When Thomas got wind of its development in 2019 he immediately asked “could the Icom IC-705 be a shortwave listeners holy grail receiver?”. I usually wince a little when I hear “holy grail” because it means very different things to different people, it’s also a moving target with many people aiming at the spot where it was decades ago. But Thomas certainly had a very level-headed assembly of technical performance, quality and practicality requirements in mind when he used that term, and I thought he might be onto something!

There are some excellent, trustworthy reviews of the IC-705 out there. The following is not one of them, I just want to share an opinionated breakdown on why I think this is an interesting radio for SWLs/BCLs indeed, also deliberately ignoring that it’s actually a transceiver.

Jumping shop

While the era of superhet/DSP-supported tabletop holy grails ended with the discontinuation and sell-off of the last survivors more than a decade ago, powerful PC-based SDR black boxes were taking over the mid-range segment and it became very slim pickings for standalone SWL receivers: Thomas just recently summed up the remaining options here.

Between the steady supply of inexpensive yet serviceable Chinese portables, upgraded with a least-cost version of DSP technology, and the remnants of the high end sector there’s very little left to put on the wish list for Santa – that doesn’t need to be paired with a computer that is.

No surprise that SWLs/BCLs in search of new quality toys with tangible controls are taking a squint over the fence to the ham transceiver market: Hams are still being served the best and the latest in radio technology in all shapes and sizes, and even entry-level rigs usually come with feature-rich general coverage receivers. But transceivers never had SWLs much in their focus in the past decades, and particularly not BCLs: Frontend adaptation, additional AM filters, switches and functions would’ve meant increasing costs and so transceivers were never perfected for that purpose. DSP and SDR technology allowed for improvements on that without actually adding (much) hardware and so some interesting alternatives surfaced in the past years, but most of them still come with little downers, at least for BCLs.

The silence of Radio Canada International (Open Canada)

The former head of CBC News laments the evisceration of CBC’s international service and Canada’s shrinking voice in the world

For a country that once regarded itself as one of the world’s leading middle powers, Canada’s voice on the international scene is a strikingly quiet one these days. It reminds me of the line from that famous “dead parrot” sketch in Monty Python: “bereft of life, it rests in peace.”

The latest sign of this is the decision by CBC/Radio-Canada to implement changes that have effectively smothered Radio Canada International (RCI), its fabled global audio and online service that has helped serve as “Canada’s Voice to the World” for more than a half century.

In a December announcement replete with CBC doublespeak, the CBC unveiled a “major transformation” of RCI that, it claimed, would ensure RCI remains “a strong and relevant voice” in this century’s media landscape. Not surprisingly, the practical impact of these changes is precisely the opposite.

Flipping RCI’s historic mission on its head, the service will now focus more on ethnic minorities within Canada rather than on continuing to produce programs tailored uniquely for international audiences. More than half of RCI’s beleaguered staff have been laid off.

This latest CBC battering of RCI — a pattern that has gone on for decades — triggered considerable criticism. In February, a group of 32 prominent Canadians sent an open letter to Prime Minister Justin Trudeau and other senior government ministers urging that the CBC scrap its planned strategy and appoint an independent committee to plan a rebuild of the international service: “In an interconnected world in search of truth, facts and honest journalism, countries like Canada cannot abdicate their role on the world stage.” Its signatories included former prime minister Joe Clark, former foreign affairs minister Lloyd Axworthy, former UN ambassador Stephen Lewis, actor Donald Sutherland and author Naomi Klein.

Live streams go down across Cox radio & TV stations in apparent ransomware attack (The Record)

Live streams for radio and TV stations owned by the Cox Media Group, one of the largest media conglomerates in the US, have gone down earlier today in what multiple sources have described as a ransomware attack.

The incident took place earlier this morning and impacted the internal networks and live streaming capabilities for Cox media properties, such as web streams and mobile apps. Official websites, telephone lines, and normal programming remained running but some live programming could not go on air as scheduled.

“This morning we were told to shut down everything and log out our emails to ensure nothing spread. According to my friends at affiliate stations, we shut things down in time to be safe and should be back up and running soon,” a Cox employee shared in a private conversation earlier today.

Asheville Radio Museum reopens to public after months-long pandemic closure (WLOS)

The Asheville Radio Museum reopened to the public Saturday, June 5, following a months-long closure due to the pandemic.

The museum, located on the campus of A-B Tech, and closed in November to follow the campus’s COVID-19 protocol to protect students and staff.

Asheville Radio Museum boasts a premier collection of vintage radios with the goal to educate, demonstrate and fascinate visitors about the importance of the radio, which was named the second most important invention of the twentieth century on the Science Channel.

Saturday’s reopening was highlighted by the addition of newly-procured radios as well as refreshed displays throughout the museum. Continue reading…

Aluminium-Ion battery development (Southgate ARC)

The Graphene Manufacturing Group in Brisbane, Australia together with the University of Queensland have according to the GMG website developed a Graphene Aluminium-Ion Battery energy storage technology that has up to three times the capacity of a lithium-ion battery and can charge up to sixty times faster.

The battery was created by inserting aluminium atoms into perforations made in graphene planes.
The company claims that because the batteries lack an upper Ampere limit that would otherwise cause spontaneous overheating, the batteries are also safer. The stable base materials also facilitate their recycling later.

The company hopes to bring these cells to market by the end of 2021 or early 2022

Icom IC-7300 and IC-705 SWL frequency files?

Many thanks to SWLing Post contributor, Dave, who writes asking if any Icom IC-705 or IC-7300 owners have created a database of SWL frequencies that could be imported into memory. I think this is a great idea as both transceivers are quite capable shortwave listening receivers.

If you have a database file and would like to share it, please comment!

Carlos seeks clarity about another CW station

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

Today (June 5, 2021) I heard another mysterious CW transmission here in Rio Grande do Sul coast, this time on 8779 kHz, 18h31 UTC.

I did some research and this frequency is related to Rome Radio (which is no longer transmitting in CW) and a marine channel (ITU821) related to Cape Town Radio but I’m not sure:

I’m sure your readers will solve this puzzle as well.

Thanks for sharing, Carlos!
